Summary for Patent: 3,982,010

Title:	Thiazole cardiovascular agents
Abstract:	1-Amino-3-[2-thiazoloxy]-2-propanol and substituted 1-amino derivatives thereof; 3-[2-thiazoloxy]-1,2-epoxypropane 5-[thiazol-2-oxymethylene]-oxazolidine and/or N-substituted and/or 2-substituted oxazolidine, derivatives thereof and methods of preparing such compounds. The above 1-amino-3-[2-thiazoloxy]-2-propanol and derivatives exhibit .beta.-adrenergic stimulating cardiovascular activity and are useful for the treatment of abnormal heart conditions in mammals. The above 3-[2-thiazoloxy]-1,2-epoxypropane and derivatives are useful as intermediates for the aforementioned cardiovascular agents. The 5-[thiazol-2-oxymethylene]-oxazolidine and derivatives are intermediates for aforementioned cardiovascular agents. The 1-amino-3-[2-thiazoloxy]-2-propanol and derivatives can be prepared by base or acid hydrolysis of the corresponding 5-[thiazol-2-oxymethylene]-oxazolidine or derivatives; or by treatment of the corresponding 3-[2-thiazoloxy]-2,3-epoxypropane or derivative with the desired amine or amino-derivative.

Patent Claims:	1. A pharmaceutical composition, for treating cardiovascular disorders in mammals by stimulating .beta.-adrenergic receptor sites, consisting essentially of a pharmaceutically acceptable carrier and an effective amount of .beta.-adrenergic stimulating agent selected from the group consisting of a pharmaceutically acceptable salt of a compound having the formula ##SPC5## wherein one of R.sup.1 or R.sup.2 is hydrogen and the other is selected from the group consisting of hydrogen, lower alkyl, cycloalkyl having 3 through 7 ring atoms, lower alkenyl, phenyl, phenylalkyl having up to 12 carbon atoms, alkylphenyl having up to 12 carbon atoms, .alpha.-methyl-.beta.-phenylethyl, .beta.-(3,4-dimethoxyphenyl)-ethyl, hydroxy lower alkyl, (lower alkoxy) lower alkyl, and the groups having the formulas --R'X or ##EQU7## wherein R' is lower alkyl, X is morpholine, piperidine or pyrrolidine, R.sup.7 and R.sup.8 are independently hydrogen or lower alkyl and n is a whole integer of from 1 through 4; and mixtures thereof. 2. The composition of claim 1 wherein one of R.sup.1 and R.sup.2 is a substituent having a methine hydrogen atom on the carbon atom attached to the amino nitrogen atom. 3. The composition of claim 1 wherein one of R.sup.1 or R.sup.2 is hydrogen and the other is selected from the group consisting of isopropyl; hydrogen; sec-butyl; cyclopropyl; cyclopentyl; .alpha.-phenylethyl; .gamma.-phenylpropyl; .alpha.-methyl-.beta.-phenylethyl; and .beta.-(3,4-dimethoxyphenyl)-ethyl and wherein when one of R.sup.1 or R.sup.2 is .alpha.-phenylethyl, the compound is the (+) isomer. 4. The composition of claim 1 wherein said carrier is sterile water. 5. The composition of claim 1 wherein said carrier is a solid selected from the group of pharmaceutical grades of starch, lactose, sodium saccharin, sodium bisulfite and mixtures of such carriers. 6. The composition of claim 1 wherein said pharmaceutically acceptable salt is a pharmaceutically acceptable salt of 1-isopropylamino-3-(thiazol-2-oxy)-2-propanol. 7. The composition of claim 6 wherein said pharmaceutically acceptable salt is 1-isopropylamino-3-(thiazol-2-oxy)-2-propanol hydrochloride.
